rrEn :STATES PATENT IMPROVEMENT IN MACHINES FOR CUTTINGROLL-PAPER.

Specification forming part of Letters Patent No. 167,645, dated September [4, 1875 application filed February 13, 1875.

To all whom it may concern:

Be it known that we, Louis P. COHEN and IGNATZ FRANK, of the city, county, and State of New York, have invented a new and Improved Machine .for Cutting Roll-Papers, of which the following is a specification:

'In the accompanying drawing, Figure 1 represents a sectional side elevation of our improved machine for cutting roll-papers; Fig. 2, an end view 5 Fig. 3, a vertical transverse section of the same on the line c c, Fig. l; and Figs. 4. and 5, respectively, are detail views of two separate cutter-feeding mechanisms.

Similar letters of reference indicate corresponding parts.

Our invention relates to an improved machineu for cutting rolls of any width directly from the roll-papers, for telegraph-rolls and other purposes; and it consists, mainly, of movable roll-clamping standards provided with one or more revolving ring-shaped heads carrying the cutting-knives that are fed forward simultaneously by suitable mechanisms.

In the drawings, A represents the baseframe of our roll-paper-cutting machine, which I has longitudinal side racks for setting the movable intermediate and outer clampingstandards B and cutter--heads C into any desired position thereon, according to the length of the roll-paper to be cut. One end standard and cutter-head is made stationary, while the opposite and intermediate standards are set by base guide-pieces and oog-wheels in the usual manner. All the roll-clamping standards B may be provided with cutter-heads when it is desired to cut the roll at one operation into a number of smaller sections, or only the outer standards may be arranged With cutter-heads, as found most convenient. A central longitudinal shaft, D, which is driven by steam or other power in connection with suitable reversinggear, transmits, by cog-wheels a, (which are keyed laterally by a longitudinal rib to the shaft, but made to slide thereon in longitudinal direction' with the standards,) rotary motionv to the ringshaped cutter-heads C. One or more cuttingknives, C', are guided in suitable grooves of the heads, preferably two of them at diametrcally Opposite points, and in parallel but nearly radial direction to the center of the head, and are fed forward for gradually cutv vting oft' a roll-section, eitherby means of a spirally-grooved disk-plate, E, which is applied stationary over the revolving head and engages projecting lugs e of the knives, as shown in Figs. 1 and 4, or by a gear-wheel mechanism, F, that is applied to the head, and is operated by the contact with stationary arms f of the standards, as shown in Fig. 5.

The spirally-grooved diskplate seems to be preferable to the gear-Wheel feed, but we do not conne ourselves to any special mechanism for feeding and returning the cutting-knives, as different constructions may be employed for the same purpose.

The ring-shaped standards B are arranged y with arc-shaped clamping-shells g, which slide by radial arms or stems g1 in corresponding grooves ofthe standards, and are operated by a loose ring-plate, B', with handle part turning on annular guide-flanges and actin g by eccentric slots h on pins or lugs g2 of the sliding shellstems, so as to adjust the whole series of them to the roll by one motion of the operating-ring.

rlhe rolls are first inserted into the standards, the cutter-heads and intermediate standards then set into the required position, the

clamping devices are next applied, and, by

the revolving motion imparted to the cutterheads, the forward feeding of the knives and the cutting off of disk-shaped rolls of any width is produced. The motion of the shaft is then reversed, and the knives moved back, the standards and. clamps are readjusted, and the next sections cut oii, and so on, accomplishing thereby the cutting off.

of paper rolls of narrower width for telegraph and other purposes with facility, economy, and rapidity, directly'from the original rolls, without the process of winding and unwinding the paper in feeding it to the cuttingknife.

Having thus described our invention, we

claim as new and desirev to secure by Lettersv Patent- 1. A machine for cutting roll-paper into sections without unwinding, constructed of stationary and movable clamping-standards with revolving cutter-heads and simnltaneouslyof the head toward the center, and back again feeding cutting-knives, the Whole being. aron reversing the motion of the cutter-head, ranged and operated substantially in the substantially as specified.`
